swap memory

基本解釋

Caution: Requires large amount of memory and swap memory.
注意：需要大量的內(nèi)存和交換分區(qū)。
The command displays the total amount of free, used physical, and swap memory in the system, as well as the buffers used by the kernel.
該命令顯示系統(tǒng)中的空閑內(nèi)存、已使用的物理內(nèi)存和交換內(nèi)存的總量，以及內(nèi)核所使用的緩沖區(qū)。
The display changes when you swap memory pages so you need not copy an Image object from program memory to video memory; you merely change video pointers and the display changes.
當(dāng)交換內(nèi)存頁時(shí)顯示就發(fā)生更改，所以您不需要將 Image 對象從程序內(nèi)存復(fù)制到顯示內(nèi)存；您只要更改視頻指針，顯示就會發(fā)生更改。

You actually need to kind of do this and then you can swap these two numbers but it requires 50 percent more memory.
你實(shí)際上需要這樣做,然后才能交換兩個(gè)數(shù)字,但是它需要多50%的內(nèi)存。

So when I said earlier that as soon as swap returns, all of the memory allocated for swap is now useless.
我前面指明的，一旦swap返回，所有為swap分配的內(nèi)存都是無用的了。

But the moment swap returns, the moment we hit this bottom most curly brace, what conceptually happens in memory?
但是swap返回時(shí)，當(dāng)我們抵達(dá)花括號底端是，在內(nèi)存中發(fā)生了什么？

While it should be possible to swap out the memory card on the new iTunes phone for one with more capacity, the person who has seen the handset says the phone's software appears to artificially cap song storage at 25 songs, regardless of how much memory the phone has.
